To all whom it may concern.-

Be it known that I, DAVID CONN, Jr., a citizen of the United States ofAmerica, and

a resident of lVaterloo, Blackhawk county,

Iowa, have invented certain new and useful Improvements in Tractors, ofwhich the following is a specification.

My invention relates to improvements in tractors, and the object of myinvention is to provide for a tractor such means as will permit ofrocking the implement connected thereto either transversely orlongitudinally to conform it to irregularities in the ground traversed,with means for elevating or lowering the implement out of or intooperative position, such means being arranged and located as to beeasily accessible to the operator. This object I have accomplished bythe means which are hereinafter described and claimed, and which areillustrated in the accompanying drawings, in which:

Figure 1 is a left-hand side elevation of a tractor frame supplied withmy improved implement adjusting means, parts thereof being removed orbroken away to better disclose the rest of the mechanism. Fig. 2 is apartial right-hand side elevation of the means specially adopted to rockthe implementeither transversely or longitudinally with relation to themain frame. Fig. 3 is a partial right-hand side elevation of such meansas are included in the mechanism for tripping and releasing theimplement to lower it into operative position. Fig. 4 is a frontelevation of the tractor, showing the hitching means for securing theimplement to the forward part of the main frame. Fig. 5 is a detailview, enlarged, of the rear swinging suspension -means for the subframe,and Fig. 6 is a similar view of the forward suspension-means for saidsubframe, with the supporting-sleeves for the hangers shown in verticalcentral section.

Similar numerals of reference denote corresponding parts throughout theseveral views.

Referring first to Fig. 1, in which the means adopted for raising orlowering the implement with relation to the main frame are disclosed:The numerals 1 indicate the horizontal rectangular main frame mounted infront on the traction-wheels 2, and in the rear on a single pivotedcaster-wheel 51. The traction-wheels 2 have sprocket-rims 84 securedthereon concentrically, and the latwheels ter may be driven by any primemotor mounted on said frame. The said tractionare mounted to rotate onthe ends of a fixed axle 3, the latter being seated fixedly in hangers83 from the main frame 1. Underneath saidmain frame, depending therefromand'spaced apart therefrom, is a horizontal subframe 39. The forward endhas each corner provided with a sleeve 4-8 which is slidably supportedon a depending shaft 47 swingingly seated in a bearing 50 on said mainframe. The said sub-frame has each rear corner provided with a sleeve 38which is movably connected to the lower end of a depending shaft 87whose upper end is swingingly seated in a bearing 49 also secured tosaid main frame. The said shafts or hangers 47 and 37 are of lessdiameters respectively than their sleevebearings 50 and 49, and haveannular flanges at their topsresting upon the tops of saidsleevebearings, which fits them to be supported therein to swingtherefrom freely. Underneath said sub-frame 39 may be located anyimplement, such as the pair of plow-shares 62 and 63, whose beams 13 and56 respectively are fixedly connected by means of an arched bar 57,while the forward ends of said beams are connected fixedly by atransverse bar 81. The two plows may therefore act together, and aremovably connected to both said main and sub-frames by the followingdescribedconnections and hitches.

Depending medially from the forward end of the main frame 1 is ahanger-bar 7. Depending also medially from the axle 3 is anotherhanger-bar 5, and a horizontal bar 6 is connected between the bars 7 and5 by means of bolts 8 and 9. Clevises 10 and 12 are pivotally connectedwith the bar 7 and the transverse bar 81 at the forward ends of saidplow-beams respectively, while said clevises are connected flexibly bymeans of a link 11, which thus permits movement to a certain extent ofthe plow-beams in any di rection. Near the forward and rear ends of eachside of the sub-frame 39 are fixed the short hangers 16 and 40, in whichare respectively seated the lower ends of cranks 14 and 41, theuppermost ends of said cranks bein connected across the sub-frame bycross-shaftswhich are seated-to rock in the bearings 15 and 42respectively fixedly mounted on the tops'of said plow-beams.

The following means are used to raise or lower said plows into or out ofoperative position: 22 is a rock-shaft mounted transversely in hearingsin said sub-frame, and upon it is mounted a sleeve 24: adapted to rockthereon, the latter provided with forwardly-projecting crank arms 18 and58, also with a small rearwardly depending lug or catch 25, and also atits left-hand end with a short rearwardly-directed crank arm 27, whichlatter has a fixed arm 28 pivoted at its rear end to the lower end of alink 29. The upper end of said link 29 is pivoted to the forward upperend of a lever 30 medially fulcrumed on a bolt 81 extending through theleft-hand side bar of said subframe 89. A link 32 serves to pivotallyconnect the lower end of the lever 30 to the lower end of another lever83, the latter medially pivoted on a bolt or shaft 3 1 to longitudinalbars 36 mounted in the rear part of the main frame near the seat of theoperator, the uppermost end of the lever 33 having its extremity bentlaterally to serve as a foot-pedal. Like links 17 and 59 connect thecrank arms 18 and 58 respectively to the middle parts of the plow beams13 and 56. Upon the crank arm 18 is a stud 80 upon which is pivotedahook 26 extending rearwardly, and a coiled tension spring 15 isconnected between a lug as on the bottom of said hook and an eye-bar 44whose rear threaded extremity is secured adjustably in a projection 43on the rear end of said sub-frame. Pivotally connected to said crank-arm18 between the sleeve 2% and the link 1? is an arm 19 whose lower enddepends and is curved forwardly and located in the line of movement ofan up wardly-extending lug on the hook 26. The upper end of said arm hasa. hook 61 to which is connected the forward hooked end of a rod 20, therear end of said rod being bent upwardly and then laterally to form afoot-pedal 35. A cross-bar 54L with depend.- ing ends, is mediallysecured to the pedalend of the rod 20, with its ends riding slidablyupon parallel longitudinal bars 55 secured medially between thetransverse bars 52 and 53 of the main frame 1 near the seat of theoperator.

To raise the plows from their down posi tion illustrated in Figs. 1 and3, the pedal is pushed forwardly, which by means of the above-describedconnections, causes the sleeve 2 1 and the crank-arms 18 and 58 to rockrearwardly, the links 17 and 59 then lifting the plow-beams 18 and 56 upequally, the cranks 14: and 41 also rocking up. As the link 17 moves upand rearwardiy its hook 226 snaps up under the traction of said spring15 and hooks into the catch 25 on the rear side of the sleeve 24 as saidcatch rocks downwardly with the sleeve. The hook is held in engagementwith said catch which retains the plows in their uppermost or raisedposition. To

lower said plows to their former position, it is merely necessary topush the other pedal 35 forwardly, the rod 20 pushing forward the arm19, whose lower curved extremity hits the upstanding lug on the hook 26and displaces the hook from the catch 25. Since there is nocounteracting force acting upon the lever 38, the weight of the plowscauses them to drop down to their lowered position.

I have provided the following means for adjusting and holding the plowsin a desired operative position. To adjust and secure the plows inrocking them transversely t accommodate their positions to work oversloping ground, whose slope is transverse to the tractor, I employ thefollowing means. Referring to Figs. 2 and 8, 7 2 is a rack-sectorsecured to the rear part of the right hand side of the main frame 1, and71 is a hand-lever pivoted thereto and provided with a movable detentadapted to detachably adjustably engage its teeth. The end of said leverbelow its fulcrum is pivoted to a link 70, and said link is also pivotedto the rear end of a lever 66 which is medially fulcrumed on a pintle 67projected from a hanger (38 on said main frame. The forward end of saidlever is connected by means of a link with the end of a crank-arm 6 1and the latter is fixed to the right-hand end of said transverserock-shaft 22 mounted in bearings 69, in the sub-frame 39. Referring nowto Fig. 1, it will be seen that a crank on the left-hand end of theshaft 22 has its end seated in. a bearing opening in the lower end of ahanger-bar 21 fixedly depending from the main frame 1 above. It resultsfrom this arrangement of parts, that when it is desired to rock theplows to either side, it is but necessary to shift the hand-lever 71. toeither side of the middle of the sector 7 2, and the intermediateconnections will rock the shaft 22 and its crank appropriately to rockthe plows transversely to the desired extent, but when the lever-detentis left engaged with the middle of the sector, the plows will remainlevel. To rock said plows longitudinally relatively to said main frameto place them properly for use when moving either up or down an inclinedsurface, the hand-lever 73 is employed. Said lever has a movable detentwhich may detachably adjustably engage the teeth of the rack-sector 7isecured to said main frame adjacent to the other sector, and easilywithin reach of the operator at the rear part of the tractor. A link 75pivotally connects the lower member of said lever with the rear end of alever 76, the latter being medially fulcrumed on a pintle 7 8 011 ahanger 77 secured to the main frame. The forward end of said lover ispivot-ed on a stud 7 9 projected laterally from a short bracket; 80 onthe slidebody 48. When said lever is shifted to either side of themiddle of the sector 74-, it

causes, through the cooperation of said connections the slide-body 48 toslide up or down a certain distance as desired on the hanger 47, whichraises or lowers the forward part of the main frame to likewise act uponthe plows or other implement suspended from said sub-frame. \Vhen thelever 73 is set medially on said sector, the plows are heldlongitudinally level relative to the main frame.
